1. Field of the Invention
The present invention relates generally to battery locking apparatuses, and more particularly to a battery locking apparatus for an electronic device in which a battery is securely installed and easily removed thereto and therefrom.
2. Related Art
Presently, portable electronic devices such as notebook computers which are driven by batteries installed therein. Many battery locking apparatuses are designed to install and remove batteries to and from electronic devices.
U.S. Pat. No. 5,716,730 discloses a battery case mounting structure for a portable electronic equipment. A recessed portion is formed in the battery case. A locking projecting body is formed on a main body of an electronic equipment and inserted in the recessed portion to fix the battery case. A guide portion supports the locking projecting body to be projectable from or retractable into the recessed portion so that the battery case is attachable to or detachable from the main body. A spring mechanism constantly biases the locking projecting body to project. An operating portion slides the locking projecting body to retract against a biasing force of the spring mechanism. The battery case is mounted on a mounting portion of the electronic equipment, and the operating portion is released. The distal end of the locking projecting body is inserted in the recessed portion of the battery case by the force of the spring, thereby fixing the battery case. However, because the portable electronic devices are typically carried about and used at various locations, the locking projecting body can be easily moved or released due to vibration, impact or inadvertent operation.
Accordingly, an object of the present invention is to provide a battery locking apparatus for securely installing and easily removing a battery to and from an electronic device.
To achieve the above-mentioned object, a locking apparatus for a battery in accordance with a preferred embodiment of the present invention includes a base, a resilient member secured to the base, and a first lock member. The battery includes at least one locking portion. The resilient member includes a stop portion. The first lock member defines a first recess and a second recess, and includes at least one post. The at least one post is engaged in the at least locking portion of the battery. The first lock member is slidable between a first position and a second position. When the first lock member is slid to the first position, the stop potion of the resilient member abuts the first lock member in the first recess to secure the battery to the base. When the first lock member is slid to the second position, the stop potion of the resilient member abuts the first lock member in the second recess to release the battery from the base.
Other objects, advantages and novel features of the present invention will be drawn from the following detailed description of preferred embodiments of the present invention with the attached drawings, in which:
The battery 10 defines a pair of spaced slots 11 in a front wall thereof. Each slot 11 comprises a vertical guide portion 13 and a horizontal lock portion 12. Each guide portion 13 is bounded by a slanted face 14. A projection 15 extends from a rear wall of the battery 10.
Referring also to
The resilient member 85 has a symmetrical configuration, and comprises a central generally semi-circular stop portion 86. The stop portion 86 is extended through the third cutout 27 of the third plate 29 of the base 20. A pair of shoulders 88 extends from opposite ends of the stop portion 86 respectively. The shoulders 88 abut a main face of the third plate 29. A pair of slanted wings 87 extends from distal ends of the shoulders 88 respectively. The wings 87 abut respective fixing tabs 28 of the base 20.
The first spring 80 comprises an enlarged portion 81 at an end thereof. The enlarged portion 81 abuts an inner face of the first plate 25 of the base 20, and an opposite end of the first spring 80 abuts an end of the first lock member 40.
The second lock member 60 comprises a front panel 61, and a plurality of parallel ribs 62 arranged thereon for facilitating manual manipulation. A through hole 63 is defined in a center portion of the second lock member 60. A pair of longitudinally disposed spaced latches 64 extends rearwardly from a rear side of the front panel 61. A pair of spaced horizontal forks 67 extends rearwardly from the rear side of the front panel 61 above and below the latches 64 respectively, substantially sandwiching the latches 64 therebetween. The latches 64 and the forks 67 are extended through the first and second gaps 52 b, 53 b of the first lock member 40 respectively, such that the latches 64 snappingly engage with the second and third bottoms 52 a, 53 a of the first lock member 40.
The button 90 comprises a cylindrical main body 91. The main body 91 defines a countersink 92 in a rear end thereof, for receiving the second spring 100 therein. An L-shaped arm 93 perpendicularly extends from the rear end of the main body 91, with an end of the arm 93 pointing forward.
When the battery 10 is installed in the battery compartment 21, the projection 15 of the battery 10 is inserted in the second through hole 21 b of the battery compartment 21, and the second posts 51 of the first lock member 40 abut the slanted faces 14 of the guide portions 13 of the slots 11. The battery 10 is pressed upwardly, and the second posts 51 slide along the slanted faces 14. Accordingly, the combined first lock member 40, second lock member 60 and button 90 is moved in direction N until the stop portion 86 of the resilient member 85 rides over the protrusion 45 of the first lock member 40 to engage in the first recess 43, so that the first lock member 40 is in a locked position. Simultaneously, the arm 93 of the button 90 is engagingly received in the second cutout 31 of the second plate 30 of the base 20, and the second posts 51 are received in the lock portions 12 of the slots 11 of the battery 10. Thus the battery 10 is secured in the base 20.
It is understood that the invention may be embodied in other forms without departing from the spirit thereof. Thus, the present examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein.
